Plug chop shows a nice brown plug with a 40 pilot 95 main. But I still can't get rid of this bog from 1/2 to wot. Doesn't seem to change no matter where I move the clip on the needle or a main change from 95 to 110

Then put needle in the middle and jet down till it wont bog then fine tune the needle. What are you running for an air filter? Pull it off and run it with the 95 and see what happens. I had mine fourstroke bad in the top end untill i got the uni filter.

After a solid 8 hours of playing with jetting with no success I put the stock gearing back in and it runs like a champ.
